Antigen Detection Kit

An antigen detection kit is a rapid diagnostic test suitable for point-of-care testing that directly detects the presence or absence of an antigen.

Kit performance advantage

1. Quick and easy: Put throat swab sample into virus preservation solution and extraction (Sample collection should conform to standard) . After extraction, the virus preservation solution is test sample; Sample Input Add 60μL test sample into detection card; Let the detection card standing about 15 minutes in room temperature. Using UV light to obtainFinal Result 

2. Good Specificity: no obvious cross-reaction between N protein of common human infection coronavirus and bat source coronavirus, also no cross-reaction between the kit and influenza a/b virus, measles virus, mumps virus, rubella virus, varicella zoster virus, staphylococcus aureus, pseudomonas aeruginosa, etc. 

3. High Sensitivity 

4. Short Window Period: Antigen detection is direct evidence of viral infection; New crown pneumonia is also contagious during the incubation period. If new crown potential patients gets the antigen detection, it could have implications for potential patients.;There is a window period for antibody detection. Detection antigen has a high probability to obtain positive results at that time. The results could provide strong evidence for the disease evaluation.
